One way to ensure the game never recovers players is to go radio silent on the game. Even the smallest bug fix will cause some video game journalist to write about it, or some video creator to make a video on it. The new fixes for station LOD and Capital Ship issues should have a Steam page update about them and so on. Communication is the best way to keep alive. Potential new players, if they see the last update was too old, will just pass. But if they see anything fresh at all, it can bring them in. I know it's not worth it in the short run to dedicate dev time, due to sales not covering the cost of the dev salary, but in the long term it may be worth it to just have something happening every couple weeks. Please post news to the regular channels such as Steam page, here and Discord, among wherever else, to ensure there's always something fresh regarding the game for people to view.
